realistic muzzle flash

http://youtu.be/tpsaX9kL7bQ <--- click this link to see realistic muzzle flare, duplicate the original footage, then grade it so it is brighter, and looks like the whole layer is glowing, then move it down below the original footage....then mask on the araes you want the glow to appear in, you can do more advanced versions of these effects by adding shadows and reflections.... hope you enjoy!! )
